This application is a Continuation of and claims the benefit of priority to U.S. application Ser. No. 10/004,926, filed on Dec. 5, 2001 and entitled “Efficiently Identifying Television Stations in a User Friendly Environment, the contents of which are hereby incorporated by reference.

TECHNICAL FIELD

The present invention relates to the field of broadcasting technology, and more particularly to allowing a user of a unit configured to receive television broadcast signals the ability to efficiently identify television stations in a user friendly environment.

BACKGROUND INFORMATION

Television broadcasting technology has improved tremendously since its inception. Today, television signals are broadcast on the airwaves through cables and via satellite. The number of television stations accessible today has increased from one to hundreds of stations. To select a program to view, many viewers may perform what is commonly referred to as “channel surfing” until they find a channel that has a desired program. Channel surfing may refer to the process of using the channel “+” or “−” button on a remote control to sequentially view each channel However, channel surfing may involve the television viewer spending an inordinate amount of time in searching for the desired channel

Channel surfing may be avoided if the television viewer recalls the particular channel(s) airing the programs of interest. For example, suppose a television viewer desires to watch the news. Under the current technology, the television viewer may have to sequentially view each channel to find a station airing news or else recall the particular television channels that air news programs However, the television viewer may not be able to recall which particular television channels air news programs Furthermore, the television viewer may not know or be able to recall which television channels air news programs at the particular time of day the viewer desires to watch the news. Furthermore, the television viewer may not know if unscheduled news programs are airing. Subsequently, the television viewer's search for particular channels airing programs of interests may be inefficient and time consuming.

It would therefore be desirable for the television viewer to efficiently identify television stations of interest in a user-friendly environment.

SUMMARY

The problems outlined above may at least in part be solved in some embodiments by displaying folders of classifications where each folder may comprise indications, e.g., icons, associated with television stations, e.g., CNN™, that a viewer may select in order to view that particular television station.

In one embodiment of the present invention, a method for identifying television stations in a user-friendly environment may comprise the step of an entertainment unit receiving broadcast signals for a plurality of television stations, e.g., ESPN™, CNN™. Furthermore, the broadcast signals may include tags for identifying a classification associated with each of the television stations broadcasted. A classification may refer to the type of broadcast, e.g., news, sports, soap operas, travel, cartoons, movies, etc., being broadcasted by that television station. The tags may further comprise content information associated with the television programs currently airing on the television stations broadcasted.

A determination may be made as to whether the received broadcast signals include tags with classification information, i.e., the classifications associated with each of the television stations broadcasted. If there are no tags with classification information in the received broadcast signals, then one or more folders, e.g., news folder, comprising one or more indications, e.g., icons, associated with one or more television stations, e.g., CNN™, may be displayed on the entertainment unit according to a base set.

Each folder, e.g., news folder, may comprise one or more indications, e.g., icons, associated with the classification of that folder, e.g., news folder. That is, each folder, e.g., news folder, may comprise one or more indications, e.g., icons, associated with television stations, e.g., CNN™, that air television programs that are classified within the same classification of the folder, e.g., news folder. The indications, e.g., icons, of television stations in the same classification as the folder, e.g., news folder, may be displayed on the entertainment unit upon the viewer of the entertainment unit selecting that folder.

If, however, there are tags with classification information in the received broadcast signals, then the tags may be compared with a list of one or more classifications associated with one or more television stations stored in a storage unit. In another embodiment, the list of one or more classifications associated with one or more television stations may be stored in a database. The database may be coupled to the entertainment unit such as via a network, e.g., LAN, WAN.

A determination may then be made as to whether there is a difference between the list of one or more classifications associated with one or more television stations and the tags. If there is no difference, then one or more folders comprising one or more indications, e.g., icons, associated with one or more television stations may be displayed on the entertainment unit according to the base set.

If, however, there is a difference between the list of one or more classifications associated with one or more television stations and the tags, then the list may be updated. The updated list may then become the base set list of one or more classifications associated with one or more television stations. One or more folders comprising one or more indications, e.g., icons, associated with television stations may then be displayed on the entertainment unit according to the updated base set.

Upon displaying one or more folders, e.g., news folder, according to the base set or updated base set, a determination may be made as to whether the entertainment unit received an input to add or delete a particular folder to be displayed or withdrawn from the display of the entertainment unit, respectively, by the viewer of the entertainment unit. If the entertainment unit received an input to add or delete a particular folder to be displayed or withdrawn from the display, respectively, then a particular folder may be added or deleted.

If the entertainment unit did not receive an input to add or delete a particular folder to be displayed or withdrawn from the display, respectively, then a determination may be made as to whether the entertainment unit received an input to add or delete a particular indication, e.g., icon, associated with a particular classification, e.g., news, sports, soap operas, travel, cartoons, movies, of a particular folder. If the entertainment unit received an input to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from the display of the entertainment unit, respectively, then a particular indication, e.g., icon, may be added or deleted.

If the entertainment unit did not receive an input to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from the display, respectively, then the current display of one or more folders and/or one or more indications, e.g., icons, may continue.

Upon adding or deleting a particular folder or a particular indication, e.g., icon, or continuing to display the current display of one or more folders and/or one or more indications, e.g., icons, a determination may be made as to whether the entertainment unit received an input to select a particular indication, e.g., icon of CNN™, associated with a particular classification, e.g., news, of a particular folder, e.g., news folder. If the entertainment unit received an input to select a particular indication, e.g., icon of CNN™, from the viewer of the entertainment unit, then the television station, e.g., CNN™, associated with the selected indication, e.g., icon of CNN™, may be displayed.

If the entertainment unit did not receive an input to select a particular indication, e.g., icon of CNN™, from the viewer of the entertainment unit, then the entertainment unit may again determine if the received broadcast signals include tags with classification information, i.e., the classifications associated with each of the television stations broadcasted, in order to determine if the classifications for the television stations have changed. Tags may be inserted in an analog or digital broadcast signal periodically, e.g., approximately every three seconds, or continuously in the broadcast signal. Subsequently, the display of the folders and/or indications may have to be updated as explained above as the classifications for the television stations may change. For example, a television station may air a movie from 8:00 p.m. to 10:00 p.m. and the news from 10:00 p.m. to 11:00 p.m. Subsequently, the indication, e.g., icon, associated with that television station may be moved from one folder to another.

In one embodiment of the present invention, a method for identifying television stations of interest based on content specified by the viewer of the entertainment unit may comprise the step of the entertainment unit receiving broadcast signals that include tags where the tags may comprise content information associated with television programs currently airing on the television stations broadcasted. In one embodiment, the content information may be in the form of keywords. For example, a football game featuring the University of Michigan Wolverines may be associated with the keywords “University of Michigan.” These keywords may be stored in a storage unit or in a database coupled to the entertainment unit via a network, e.g., LAN, WAN, or in any other type of storage device.

Upon the entertainment unit receiving input, e.g., “University of Michigan”, to identify one or more television stations that are currently airing television programs with matching content inputted from the viewer of the entertainment unit, a comparison may then be made between the content information stored in the storage device and the input received from the viewer of the entertainment unit.

A determination may then be made as to whether there is a match between the input received from the viewer of the entertainment unit and the content information stored in the storage device. If there is not a match, then a notification may be displayed on the entertainment unit indicating that the input received was not identified in any content of the television programs currently airing.

If there is a match, then one or more indications, e.g., icons, associated with one or more television stations airing television programs whose content matched the input received from the viewer of the entertainment unit may be displayed on the entertainment unit. In one embodiment, a profile associated with each indication, e.g., icon, may be displayed on the entertainment unit providing further detailed information, e.g., football game, movie, about the television program currently airing on the television station associated with the indication. By learning further detailed information about the television program currently airing on the television station associated with the indication, the viewer may then decide whether to view that television program.

The entertainment unit may then receive input from the viewer to select a particular indication, e.g., icon, associated with a particular television station. The television station, e.g., CNN™, associated with the selected indication, e.g., icon of CNN™, may subsequently be displayed on the entertainment unit.

The foregoing has outlined rather broadly the features and technical advantages of one or more embodiments of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention.

The development of computerized information distribution and interconnected computers allow users to link with other computer networks, and retrieve vast amounts of electronic information heretofore unavailable in an electronic medium. Such electronic information increasingly displaces more conventional techniques of information transmission, such as newspapers and magazines. The term “Internet” may refer to a collection of computer networks interconnected over communication links that utilize standard protocols well known in the art of computer networking.

A basic computer network, including the Internet, typically utilizes a client/server architecture. A “client” may refer to a computer that accesses shared network resources provided by another computer commonly referred to as a server.

A “server” may typically be a remote computer system accessible over a communications medium such as the Internet. The server may scan and search for information sources. Based upon information requested by the user, the server may provide video transmission, e.g., streaming video, to the user. Referring to FIG. 1, entertainment unit 101 may be a client which is capable of receiving information such as broadcast signals. Broadcast signals may be provided by broadcast networks 104, web sites 105, local affiliates 106 and local cable provider 107. However, as would be recognized by those of ordinary skill, the principles of the present invention as discussed hereinbelow are not restricted by a particular signal source.

FIGS. 3A and 3B—Method for Identifying Television Stations in a User Friendly Environment

FIGS. 3A and 3B are a flowchart of one embodiment of the present invention of a method 300 for identifying television stations in a user-friendly environment. As stated in the Background Information section, channel surfing may be avoided if the television viewer recalls the particular channel(s) airing the programs of interest. For example, suppose a television viewer desires to watch the news. Under the current technology, the television viewer may have to sequentially view each channel to find a station airing news or else recall the particular television channels that air news programs However, the television viewer may not be able to recall which particular television channels air news programs Furthermore, the television viewer may not know or be able to recall which television channels air news programs at the particular time of day the user desires to watch the news. Furthermore, the television viewer may not know if unscheduled news programs are airing. Subsequently, the television viewer's search for particular channels airing programs of interests may be inefficient and time consuming. It would therefore be desirable for the television viewer to efficiently identify television stations of interest in a user-friendly environment. Method 300 is a method for efficiently identifying television stations of interest. Method 500, as discussed in FIG. 5, is a method for efficiently identifying television stations of interest based on content specified by the viewer of entertainment unit 101.

Referring to FIGS. 3A and 3B, in step 301, entertainment unit 101 (FIG. 2) may receive broadcast signals. As discussed above in conjunction with FIGS. 1 and 2, entertainment unit 101 may be configured to receive a broadcast signal from a broadcast network 109 by a tuner 112, that may be embodied in hardware or software, receiving the broadcast signal through an antenna system depicted by broadcast antenna 113 and receiver antenna 114. Entertainment unit 101 may further be configured to receive a multiplicity of broadcast signals from cable provider 107 by cable television converter 110, that may be embodied in hardware or software, receiving the broadcast signal through hardwired cable 111. Entertainment unit 101 may further be configured to receive a multiplicity of broadcast signals from multimedia provider 108 via telephone service provider 102. Multimedia provider 108 may be configured to provide broadcast signals from a variety of information sources 103, e.g., broadcast networks 104, web sites 105, local affiliate 106, cable provider 107. It is noted that entertainment unit 101 may be configured to receive broadcast signals using other means recognized by an artisan of ordinary skill in the art and that such embodiments employing such means would fall within the scope of the present invention.

The broadcast signals may include tags for identifying a classification associated with each of the television stations broadcasted. A classification may refer to the type of broadcast, e.g., news, sports, soap operas, travel, cartoons, movies, etc., being broadcasted by that television station. In one embodiment, tags may further comprise content information associated with the television programs currently airing on the television stations broadcasted. A description of identifying television stations of interest based on the content of the television programs currently airing is provided in FIG. 5.

In one embodiment, tags may be superimposed with the analog broadcast signals by inserting tags periodically, e.g., approximately every three seconds, or continuously in the vertical blanking interval of the signal or in either the audio or live video stream. It is noted there are numerous means of superimposing tags with analog broadcast signals and that such means would be recognized by an artisan of ordinary skill in the art. It is further noted that embodiments employing such means would fall within the scope of the present invention.

In one embodiment, tags may be periodically, e.g., approximately every three seconds, or continuously inserted in the digital broadcast signals associated with the particular video and audio data stream. It is noted there are numerous means of inserting tags in the digital broadcast signals and that such means would be recognized by an artisan of ordinary skill in the art. It is further noted that embodiments employing such means would fall within the scope of the present invention.

In one embodiment, the tags may be inserted in the analog broadcast signals by broadcaster 109. In another embodiment, the tags may be inserted in the analog or digital broadcast signals by local cable provider 107. In another embodiment, the tags may be inserted in the analog or digital broadcast signals by multimedia provider 108. It is noted that the tags may be inserted in the analog or digital broadcast signals by other entities not shown and that the above description is illustrative.

In step 302, a determination may be made as to whether the received broadcast signals include tags with classification information, i.e., the classifications associated with each of the television stations broadcasted. If there are no tags with classification information in the received broadcast signals, then one or more folders comprising one or more indications, e.g., icons, associated with one or more television stations may be displayed on display 216 (FIG. 2) according to the base set in step 303 as illustrated in FIG. 4.

FIG. 4 illustrates an embodiment of the present invention of displaying one or more folders comprising one or more indications, e.g., icons, associated with one or more television stations displayed on display 216. Referring to FIG. 4, one or more folders 401A-D associated with one or more classifications, e.g., news, sports, soap operas, travel, cartoons, movies, may be displayed on display 216. Folders 401A-D may collectively or individually be referred to as folders 401 or folder 401, respectively. Each folder may be associated with a particular classification. For example, folder 401A may be associated with news. Folder 401B may be associated with sports. Folder 401C may be a folder 401 created by the viewer of entertainment unit 101 as discussed further below. Folder 401D may be associated with movies. It is noted that any number of folders 401 may be displayed on display 216 and that FIG. 4 is illustrative.

Each folder 401 may comprise one or more indications, e.g., icons, associated with the classification of that folder 401. That is, each folder 401 may comprise one or more indications, e.g., icons, associated with television stations that air television programs that are classified within the same classification of folder 401. These indications, e.g., icons, may be displayed on display 216 upon the viewer of entertainment unit 101 selecting folder 401 as illustrated by arrow 403. In one embodiment, the viewer of entertainment unit 101 may select a particular folder 401 to view the indication(s) of television stations in the same classification as folder 401 by selecting mouse 214 when the cursor rests on folder 401. In another embodiment, the viewer of entertainment unit 101 may select a particular folder 401 to view the indication(s) of television stations in the same classification as folder 401 via remote control 220 (FIG. 2). For example, folder 401A associated with news may be selected to display one or more indications of television stations that air news such as CNN™ 402A, CNN Headline News™ 402B, MSNBC™ 402C and Fox News™ 402D. It is noted that each folder 401 may comprise any number of indications, e.g., icons, associated with television stations and that FIG. 4 is illustrative.

Referring to step 302 of FIGS. 3A and 3B, if there are tags with classification information in the received broadcast signals, then tags may be compared, in step 304, with a list of one or more classifications associated with one or more television stations stored in storage unit 207 (FIG. 2). In another embodiment, the list of one or more classifications associated with one or more television stations may be stored in a database. The database may be coupled to entertainment unit 101 such as via a network, e.g., LAN, WAN.

A determination may then be made as to whether there is a difference between the list of one or more classifications associated with one or more television stations and the tags in step 305. If there is no difference, then one or more folders comprising one or more indications, e.g., icons, associated with one or more television stations may be displayed on display 216 according to the base set in step 303.

If there is a difference between the list of one or more classifications associated with one or more television stations and the tags, then the list may be updated in step 306. The updated list may then become the base set list of one or more classifications associated with one or more television stations.

In step 307, one or more folders 401 comprising one or more indications, e.g., icons, associated with television stations may be displayed on display 216 as illustrated in FIG. 4 according to the updated base set.

In step 308, a determination may be made as to whether entertainment unit 101 received an input to add or delete a particular folder 401 to be displayed or withdrawn from display 216, respectively, by the viewer of entertainment unit 101. In one embodiment, the viewer of entertainment unit 101 may input to add or delete a particular folder 401 to be displayed or withdrawn from display 216, respectively, via speech. That is, the viewer may verbally communicate to add or delete a particular folder 401 where the verbal communications may be received by microphone 217 and recognized by speech recognition software stored in storage unit 207 (FIG. 2) or in application 204 (FIG. 2). In another embodiment, the viewer of entertainment unit 101 may input to add or delete a particular folder 401 to be displayed or withdrawn from display 216, respectively, via keyboard 215. In another embodiment, the viewer of entertainment unit 101 may input to add or delete a particular folder 401 to be displayed or withdrawn from display 216, respectively, via remote control 220. In another embodiment, the viewer of entertainment unit 101 may input to add or delete a particular folder 401 to be displayed or withdrawn from display 216, respectively, via mouse 215. It is noted there are numerous means of the viewer inputting to entertainment unit 101 to add or delete a particular folder 401 to be displayed or withdrawn from display 216 and that such means would be recognized by an artisan of ordinary skill in the art. It is further noted that embodiments employing such means would fall within the scope of the present invention.

If entertainment unit 101 received an input to add or delete a particular folder 401 to be displayed or withdrawn from display 216, respectively, from the viewer of entertainment unit 101, then a particular folder 401 may be added or deleted in step 309.

If entertainment unit 101 did not receive an input to add or delete a particular folder 401 to be displayed or withdrawn from display 216, respectively, from the viewer of entertainment unit 101, then, in step 310, a determination may be made as to whether entertainment unit 101 received an input to add or delete a particular indication, e.g., icon, associated with a particular classification, e.g., news, sports, soap operas, travel, cartoons, movies, of a particular folder 401. In one embodiment, the viewer of entertainment unit 101 may input to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from display 216, respectively, via speech. That is, the viewer may verbally communicate to add or delete a particular indication, e.g., icon, where the verbal communications may be received by microphone 217 and recognized by speech recognition software stored in storage unit 207 or in application 204. In another embodiment, the viewer of entertainment unit 101 may input to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from display 216, respectively, via keyboard 215. In another embodiment, the viewer of entertainment unit 101 may input to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from display 216, respectively, via remote control 220.

It is noted there are numerous means of the viewer inputting to entertainment unit 101 to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from display 216 and that such means would be recognized by an artisan of ordinary skill in the art. It is further noted that embodiments employing such means would fall within the scope of the present invention.

If entertainment unit 101 received an input to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from display 216, respectively, from the viewer of entertainment unit 101, then a particular indication, e.g., icon, may be added or deleted in step 311.

If entertainment unit 101 did not receive an input to add or delete a particular indication, e.g., icon, to be displayed or withdrawn from display 216, respectively, from the viewer of entertainment unit 101, then the current display of one or more folders and/or one or more indications, e.g., icons, may continue in step 312.

A determination may be made in step 313 as to whether entertainment unit 101 received an input to select a particular indication, e.g., icon of CNN™ 402A, associated with a particular classification, e.g., news, of a particular folder 401, e.g., news folder 401A. In one embodiment, the viewer of entertainment unit 101 may input to select a particular indication, e.g., icon of CNN™ 402A, via speech. That is, the viewer may verbally communicate to select a particular indication, e.g., icon of CNN™ 402A, where the verbal communications may be received by microphone 217 and recognized by speech recognition software stored in storage unit 207 or in application 204. In another embodiment, the viewer of entertainment unit 101 may input to select a particular indication, e.g., icon of CNN™ 402A, via keyboard 215. In another embodiment, the viewer of entertainment unit 101 may input to select a particular indication, e.g., icon of CNN™ 402A, via remote control 220. In another embodiment, the viewer of entertainment unit 101 may input to select a particular indication via mouse 215. It is noted there are numerous means of the viewer inputting to entertainment unit 101 to select a particular indication, e.g., icon of CNN™ 402A, and that such means would be recognized by an artisan of ordinary skill in the art. It is further noted that embodiments employing such means would fall within the scope of the present invention.

If entertainment unit 101 received an input to select a particular indication, e.g., icon of CNN™ 402A, from the viewer of entertainment unit 101, then, in step 314, the television station, e.g., CNN™, associated with the selected indication, e.g., icon of CNN™ 402A, may be displayed on display 216.

If entertainment unit 101 did not receive an input to select a particular indication, e.g., icon of CNN™ 402A, from the viewer of entertainment unit 101, then, in step 302, entertainment unit 101 may again determine if the received broadcast signals include tags with classification information, i.e., the classifications associated with each of the television stations broadcasted, in order to determine if the classifications for the television stations have changed. As stated above, tags may be inserted in the analog or digital broadcast signals periodically, e.g., approximately every three seconds, or continuously in the broadcast signals. Subsequently, the display of folders 401 and/or indications may have to be updated as explained in steps 304-306 as the classifications for the television stations may change. For example, a television station may air a movie from 8:00 p.m. to 10:00 p.m. and the news from 10:00 p.m. to 11:00 p.m. Subsequently, the indication, e.g., icon, associated with that television station may be moved from one folder 401 to another. It is further noted that in one embodiment when entertainment unit 101 is deactivated, tuner 112, whether embodied in hardware or software, may be configured to continue to receive tags. These tags may then be compared with the base set list of one or more classifications associated with one or more television stations to determine if the base set list needs to be updated.

It is noted that method 300 may be executed in a different order presented and that the order presented in the discussion of FIGS. 3A and 3B is illustrative. It is further noted that certain steps may be executed almost concurrently.

FIG. 5—Method for Efficiently Identifying Television Stations of Interest Based on Content Specified by the Viewer of the Entertainment Unit

FIG. 5 is a flowchart of one embodiment of the present invention of a method 500 for identifying television stations of interest based on content specified by the viewer of entertainment unit 101.

In step 501, entertainment unit 101 (FIG. 2) may receive broadcast signals incorporated with tags where the tags may comprise content information associated with television programs currently airing on the television stations broadcasted. In one embodiment, the content information may be in the form of keywords. For example, a football game featuring the University of Michigan Wolverines may be associated with the keywords “University of Michigan.” These keywords may be stored in storage unit 207 or in a database coupled to entertainment unit 101 via a network, e.g., LAN, WAN, or in any other type of storage device.

In step 502, entertainment unit 101 may receive input, e.g., “University of Michigan”, to identify one or more television stations that are currently airing television programs with matching content inputted by the viewer of entertainment unit 101. As stated above, the tags inserted in the broadcast signals may comprise content associated with television programs currently airing in the form of keywords that may be stored in a storage device, e.g., storage unit 207. In one embodiment, the viewer of entertainment unit 101 may input keywords to be searched in the storage device via speech. That is, the viewer may verbally communicate keywords that may be received by microphone 217 and recognized by speech recognition software stored in storage unit 207 or in application 204. In another embodiment, the viewer of entertainment unit 101 may input keywords to be searched in the storage device via keyboard 215. In another embodiment, the viewer of entertainment unit 101 may input keywords to be searched in the storage device via remote control 220. In another embodiment, the viewer of entertainment unit 101 may input keywords to be searched in the storage device via mouse 215. It is noted there are numerous means of the viewer inputting keywords to be searched in a storage device, e.g., storage unit 207, and that such means would be recognized by an artisan of ordinary skill in the art. It is further noted that embodiments employing such means would fall within the scope of the present invention.

In step 503, a comparison may be made between the content information stored in the storage device, e.g., storage unit 207, and the input received from the viewer of entertainment unit 101.

In step 504, a determination may be made as to whether there is a match between the input received from the viewer of entertainment unit 101 and the content information stored in the storage device, e.g., storage unit 207. If there is not a match, then a notification that input received in step 502 was not identified in any content of the television programs currently airing may be displayed on display 216 in step 505.

If there is a match, then one or more indications, e.g., icons, associated with one or more television stations airing television programs whose content matched the input received from the viewer of entertainment unit 101 may be displayed on display 216 in step 506. In one embodiment, a profile associated with each indication, e.g., icon, may be displayed on display 216 providing further detailed information, e.g., football game, movie, about the television program currently airing on the television station associated with the indication. By learning further detailed information about the television program currently airing on the television station associated with the indication, the viewer may then decide whether to view that television program.

In step 507, entertainment unit 101 may receive input to select a particular indication, e.g., icon, associated with a particular television station from a viewer of entertainment unit 101. In one embodiment, the viewer of entertainment unit 101 may input to select a particular indication, e.g., icon of CNN™ 402A, via speech. That is, the viewer may verbally communicate to select a particular indication where the verbal communications may be received by microphone 217 and recognized by speech recognition software stored in storage unit 207 or in application 204. In another embodiment, the viewer of entertainment unit 101 may input to select a particular indication via keyboard 215. In another embodiment, the viewer of entertainment unit 101 may input to select a particular indication via remote control 220. In another embodiment, the viewer of entertainment unit 101 may input to select a particular indication via mouse 215. It is noted there are numerous means of the viewer inputting to entertainment unit 101 to select a particular indication, e.g., icon of CNN™ 402A, and that such means would be recognized by an artisan of ordinary skill in the art. It is further noted that embodiments employing such means would fall within the scope of the present invention.

In step 508, the television station, e.g., CNN™, associated with the selected indication, e.g., icon of CNN™ 402A, may be displayed on display 216.

It is noted that method 500 may be executed in a different order presented and that the order presented in the discussion of FIG. 5 is illustrative. It is further noted that certain steps in method 500 may be executed almost concurrently.
